For all of your questions Meta would need a huge research/GPU investment, so that still holds.

In any case if I have to guess, we will see shallow things like the Sora app, a video generation tiktok social network and deeper integration like fake influencers, content generation that fits your preferences and ad publishers preferences

a more evil incarnation of this might be a social network where you aren't sure who is real and who isn't. This will probably be a natural evolution of the need to bootstrap a social network with people and replacing these with LLMs
